A Preliminary Study On The Length-Weight Relationship Of Sacura Boulengeri (Heemstra, 1973) From Indian Waters, Kinattumkara Bineesh, Sebastine Manju, Kallivalappil Akhilesh, Gopalakrishna Pillai Jan 2012

A Preliminary Study On The Length-Weight Relationship Of Sacura Boulengeri (Heemstra, 1973) From Indian Waters, Kinattumkara Bineesh, Sebastine Manju, Kallivalappil Akhilesh, Gopalakrishna Pillai

Turkish Journal of Zoology

Sacura boulengeri (Heemstra, 1973) is a rare serranid fish (Subfamily: Anthiinae) having very disjunct distribution in the western Indian Ocean. The rarity of the species is evident from earlier reports and, so far, no related studies on the species have been published except on taxonomy and distributional records. In the present investigation, the length-weight relationship of Sacura boulengeri was estimated to be W = 0.0777 × L2.690 (with 95% confidence intervals for b and r2). An analysis of the stomach contents revealed that sergestid shrimps and copepods were the major food items of the diet.

Profundal Oligochaete Assemblages In Palaearctic Lakes, Tarmo Timm Jan 2012

Profundal Oligochaete Assemblages In Palaearctic Lakes, Tarmo Timm

Turkish Journal of Zoology

The profundal oligochaete fauna is mostly formed of species present also in shallower waters. Endemic taxa have developed only in ancient rift lakes like Lake Baikal. "Common" lakes, mostly of glacial or volcanic origin, are too ephemeral for speciation. In the profundal of larger European oligotrophic lakes, there can occur about 10 tubificid and lumbriculid species. With a decline in dissolved oxygen in water, only 1-2 of them will remain, Tubifex tubifex often being the last survivor. In eutrophic lakes, Potamothrix hammoniensis is the climax species. In the Far East, the profundal is also inhabited by a small assortment of …

Growth Performance And Body Composition Of Kutum Fingerlings, Rutilus Frisii Kutum (Kamenskii 1901),In Response To Dietary Protein Levels, Ghaffar Ebrahimi, Hossein Ouraji Jan 2012

Growth Performance And Body Composition Of Kutum Fingerlings, Rutilus Frisii Kutum (Kamenskii 1901),In Response To Dietary Protein Levels, Ghaffar Ebrahimi, Hossein Ouraji

Turkish Journal of Zoology

A feeding trial was conducted to determine the optimal dietary crude protein requirement for Rutilus frisii kutum fingerlings. Five isoenergetic experimental diets were formulated to contain graded levels of protein (32%, 37%, 42%, 47%, and 52%). Triplicate groups of 80 kutum (average weight 0.5 g) were stocked in 250-L tanks and fed to apparent satiation 3 times a day for 8 weeks. The results indicate that the growth performance and feed utilization of kutum were significantly (P < 0.05) affected by dietary protein level. The second polynomial regression of weight gain against protein level yielded an estimated optimal dietary protein requirement of 41.6%. Weight gain, specific growth rate, and feed efficiency increased with increasing the dietary protein level from 32% to 42%, but decreased significantly (P < 0.05) with further increases in dietary protein. The protein efficiency ratio was inversely correlated with dietary protein level. Feed intake was not affected (P > 0.05) by dietary protein level. No significant difference was found in the whole-body protein, lipid, moisture, or ash contents of fish fed the …

Microtaxonomy Of Fragmenting Enchytraeus Species Using Molecular Markers, With A Comment On Species Complexes In Enchytraeids, Rut Collado, Eva Hass-Cordes, Ruediger Schmelz

Turkish Journal of Zoology

Populations of Enchytraeus that reproduce by fragmentation are distributed worldwide, but their species-level taxonomy is unresolved because morphological differences are inconclusive. Therefore, we compared the isozyme and RAPD-PCR patterns of 5 populations of fragmenting enchytraeids from widely distant localities (Japan, Iran, Greece, and Brazil). Among these populations, 3 were identified (E. japonensis, E. bigeminus, and E. dudichi) and 2 were unidentified. Multiple isozyme bands suggested polyploidy in all investigated populations. In all RAPD-PCR algorithms except 1, the fragmenting group formed a cluster separate from 2 nonfragmenting Enchytraeus species. All 5 populations were clearly separable on the levels of protein and …

The Combined Effects Of Salinity And Temperature On The Egg Hatching Rate, Incubation Time, And Survival Until Protozoal Stages Of Metapenaeus Monoceros (Fabricius) (Decapoda: Penaeidae), Mevlüt Aktaş, Nuran Çavdar Jan 2012

The Combined Effects Of Salinity And Temperature On The Egg Hatching Rate, Incubation Time, And Survival Until Protozoal Stages Of Metapenaeus Monoceros (Fabricius) (Decapoda: Penaeidae), Mevlüt Aktaş, Nuran Çavdar

Turkish Journal of Zoology

The combined effects of 3 different temperatures (24, 28, and 32 °C) and salinity levels (35, 40, and 45 g L^{-1}) on the egg hatching rate, incubation time, larval activity, and survival rate until protozoal (PZ1) stage of Metapenaeus monoceros (Fabricius) were investigated under controlled laboratory conditions. The average fertilization rate was 97.25% following spawning. The eggs were stocked in 2-L glass larval culture flasks and received 1 of 9 salinity and temperature combinations in 3 replicates. The eggs hatched in all treatments. Temperature, salinity, and their interaction had significant influences on the hatching rate of the eggs (P < 0.05). The hatching rate decreased as salinity increased and was lowest in all temperature levels at a salinity of 45 g L^{-1}. With regard to the hatching rate, the best combinations were obtained at 35 g L^{-1} and 32 °C (91.67%) and at 35 g L^{-1} and 28 °C (89.17%). The incubation time was shorter at 32 °C (11.2 h) than at 28 °C (14 h) or 24 °C (17.2 h). The development rate from the naupliar stage to the protozoal stage was best at a salinity level of 35 g L^{-1} combined with temperatures of 28 °C and 32 °C. Larval activity was also found to be best at 28 °C and 32 °C at 35 g L^{-1} and 40 g L^{-1}, as compared to that at 24 °C in all salinity levels.
